Structural Characteristics and Parameters of Tunnel Greenhouses

Span and Height
Tunnel greenhouses have a wide range of spans, with common spans including 6 meters to 9.6 meters, and heights typically ranging from 2 meters to 6 meters. The span and height can be customized according to customer needs. For example, FERTRI's MINITUNNEL greenhouse has a width of 3.5 meters and a height of 2.5 meters, making it suitable for small-area home gardening.

Shape and Design
Most are arched or tunnel-shaped structures, which effectively disperse wind forces, enhance resilience, and facilitate natural runoff of rainwater. Some high-end greenhouses (like those from J. Huete Greenhouses) use glass materials and have more complex structures, suitable for high-value crops such as flowers or medicinal plants.

Materials and Types of Tunnel Greenhouses

Covering Materials

• Plastic Film: Economical and practical, with good light transmission. Thickness: 120/150/200 micrometers; Light transmission rate: >89%; Diffusion: ≤20%; Warranty period: 6-8 years; Features UV resistance, anti-aging, and anti-drip properties.

Framework Materials
The greenhouse framework is made of hot-dip galvanized steel and accessories, providing a sturdy and durable structure with high strength and corrosion resistance. Some products incorporate modular design for easy assembly and expansion. Warranty period: 10-15 years.

Key Technical Configurations of Tunnel Greenhouses

Ventilation System: Automatically opening and closing skylights and side windows, or using fans and wet curtains for forced ventilation.

Thermal Insulation and SunShading: Internal thermal insulation curtains, external sunshading nets, combined with double-layered hollow covering materials.

Environmental Monitoring and Intelligent Control: Temperature and humidity sensors, light sensors, CO₂ concentration monitoring, with linked control equipment.

Application Scenarios of Tunnel Greenhouses

Commercial Cultivation
Used for large-scale production of vegetables, fruits, and flowers, especially off-season crops. For example, FERTRI's greenhouses can adapt to different climatic conditions and provide turnkey solutions from installation to maintenance.

Homes and Small Gardens
Mini tunnel greenhouses (like MINITUNNEL) are ideal for home gardening due to their small size and low cost, suitable for beginners.

Exhibitions and Botanical Gardens
Some greenhouse designs emphasize aesthetics, such as Gothic tunnel greenhouses, which combine functionality with ornamental value for plant displays or public education.

Technological Innovations in Tunnel Greenhouses

Regional Customization
For arid regions in cold climates, new tunnel greenhouses are equipped with rainwater collection devices, utilizing diversion membrane cloth, filtration mechanisms, and liquid level monitoring systems to efficiently recycle and utilize rainwater, reducing water waste. For tropical and subtropical regions, new tunnel greenhouses are equipped with side ventilation and flood prevention systems, optionally with insect screens to effectively prevent mosquito infestation.

Energy Conversion and Energy-saving Design
Greenhouses can be equipped with energy-saving devices such as shading systems, cold-cutting temperature control systems, sprinkler systems, and drip irrigation systems. For example, J. Huete Greenhouses' greenhouses can adjust environmental parameters based on crop needs, improving energy utilization efficiency.

Modularity and Flexibility
Hot-dip galvanized steel framework supports rapid assembly and expansion, such as hoop-style tunnel greenhouses, facilitating adjustments in scale according to planting needs.

Through structural optimization and technological innovation, tunnel greenhouses have achieved comprehensive coverage from home gardening to large-scale agricultural production. In the future, with the deepening application of intelligence and sustainable technologies, their functionality and economy will further enhance, making them important infrastructure for modern agriculture.
